IssueTracker

Thanks for the report. Can you check if you get more information about where this issue is coming from by running with the --stacktrace flag: ./gradlew assembleRelease --stacktrace?

Would it be possible for you to share a dump of the inputs to R8 that causes the compilation failure? That way we should be able to reproduce the problem.

You can generate a zip dump by running the following command. The dump contains the project's class files, Proguard configuration, etc.

./gradlew assembleRelease --no-daemon -Dcom.android.tools.r8.dumpinputtodirectory=/path/to/dumps

You can share the dump privately with christofferqa@google.com or sgjesse@google.com.

See also https://r8.googlesource.com/r8/+/refs/heads/main/doc/compilerdump.md for more details.

Sure, Thank you for reply.

Thanks for the additional details. I can see that you deleted the dump after first uploading it. Would it be possible for you to share the dump privately with christofferqa@google.com or sgjesse@google.com?

Below is the retraced stack trace for the error.

I sent it yesterday using Outlook and have just resent it using Gmail.

Thanks, I now received the dump. I was able to reproduce the issue and will start diagnosing the root cause.

Thanks again for reporting this and helping reproduce the issue.

This issue should now be fixed in R8 main. The fix should make it into the upcoming R8 4.0.22-dev, which will make it into one of the upcoming AGP versions (likely AGP 7.4 beta 1).

Thanks, very much looking forward to it.
